Curiosity Rover Sees Solar Eclipse On Mars

Every location on Mars gets an eclipse by both Phobos and Deimos twice a year.

No, only at the equator [agu.org]:

There is a narrow band, centered on the equator of Mars, within which every point is eclipsed at least once during each semiannual eclipse season. Outside that band, the density of coverage decreases slowly with increasing distance from the equator, until the limiting latitudes are reached.

BTW, a surface transit (that is a more appropriate proper term, as neither moon ever fully eclipses the Sun) was also observed by the VIking Lande 1 [nasa.gov] in the 1970's.

And for the Earth solar eclipses, over an 18.6 year cycle, are equally likely in either terrestrial hemisphere.
